Learnings:

This project was huge. Organizing it and making design choices was the hard part. I messed it the first time I tried it. https://github.com/sapienfrom2000s/chess TDD wasn't followed in this project as I was too lazy to do it. I also didn't have a clear picture about the benefits of TDD. Tests were write after adding features. Inheritance is powerful.The common properties can be pushed to parent, it helps to keep the code dry.Single responsibility principle. I am not sure if I followed it, but the idea is to split responsibilities bw classes as much as possible. Using script to open the program instead of manually telling it to interpret it with ruby again and again. Used LOAD_PATH to require files from lib instead of require_relative Powerful git ideas such as hard reset, rebasing and applying patches. Design patterns such as loosely coupled code and dependency injection
